Citizen science: eyes in the skies and on the seas
Australian citizen scientists are helping to catch shooting stars in the vast skies of outback Australia and to track the impact of climate change on species in our warming oceans.
Curtin University’s Fireballs in the Sky project invites people to use a smartphone app to record and submit the time, location, trajectory and appearance of meteors they spot.
By triangulating these reports with observations from an array of cameras in remote Western and South Australia, scientists can try to determine where the meteorite may have come from and where it landed.

Glucosamine study raises fertility concerns
Research on the effects of the popular joint supplement glucosamine has raised fears for women’s fertility, and a knee-jerk reaction from the vitamin industry, as Adelaide scientists reveal its threat to conception.

Obese dads leave kids with fat chance
An obese father increases the risk of his children and grandchildren becoming obese, even if they follow a healthy diet. That’s the implication of a series of mouse studies conducted at the University of Adelaide.
The researchers found that a father’s high-fat diet could change the molecular make-up of his sperm, leading to obesity and diabetes-like symptoms in two generations of offspring.
“With obese fathers, changes in the sperm’s microRNA molecules are linked with programming the embryo for obesity or metabolic disease later in life,” says Tod Fullston, the study’s lead author and an NHMRC Peter Doherty Fellow with the University of Adelaide’s Robinson Research Institute.
Preterm birth linked to teen school angst
Large numbers of premature-born children may be slipping under the radar, say researchers who have found brain development problems in teenagers deemed clinically normal after a late preterm birth.
Julia Pitcher and Michael Ridding, of the Robinson Research Institute, University of Adelaide, found that children born even one to five weeks premature showed reduced ‘neuroplasticity’ as teenagers. Their study provides the first physiological evidence of the link between late preterm birth and reduced motor, learning and social skills in later life.
Fresh water bounty under the sea
Future global water shortages could be alleviated by huge freshwater reserves discovered beneath the ocean floor, according to a team of Australian and international scientists.
The scientists from Adelaide, the Netherlands, USA and the UK have found half a million cubic kilometres of fresh water in undersea aquifers located off Australia, China, North America and South Africa.
These aquifers are similar to the groundwater used in much of Australia and the rest of the world for drinking water and irrigation, and so could come in handy as existing supplies dwindle.
Starch to save young lives
A fibre may help save millions of children in developing countries who die or who are left malnourished from diarrhoea each year.
Graeme Young, AM, of Flinders University, is leading a global project that will test his theory that resistant starch increases zinc absorption in the body.
Academy recognition
The Australian Academy of Science recognised five individuals for their career achievements in 2013.
- The search for dark matter was kicked off by Ken Freeman’s discovery that there wasn’t enough matter to hold spiral galaxies like ours together. Continue reading Academy recognition
Fresh Science 2013
Each year we identify early-career scientists with a discovery and bring them to Melbourne for a communication boot camp. Here are some of their stories. For more information go to freshscience.org.au
Light work makes for a better drop
New Australian technology will enable real-time monitoring of wine throughout its fermentation and maturation process, reducing spoilage and improving quality.
The “Smart Bung” technology has been pioneered at the University of Adelaide by the Institute for Photonics & Advanced Sensing (IPAS) and the School of Agriculture, Food and Wine (SAFW). The work is led by Prof Tanya Monro, Director of IPAS.
An optical fibre sensor incorporated into the bung of a wine cask can detect substances that might cause the wine to spoil. The optical fibres have tiny holes that take up minute samples of the wine. The sensor shines light through the fibres to determine the concentration of certain important chemicals, such as hydrogen peroxide and sulphur dioxide—all without having to open the cask. The system will enable continuous, real-time cask-by-cask monitoring and an immediate response if problems are detected.
